DETACHABLE TOOL-HANDLE.

Specification of Letters Patent.

Patented Dec. 3, 1907'.

Application filed June 21, 1906. Serial No. 322.788.

To all whom it may concern:

Be it known that I, JoHN B. ISABEL, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Detachable Tool-Handles,

' for the purpose of dressing or sharpening the former, and in which also it is necessary, for the purpose of saving time, to quickly re-connect the handle with the tool-head and have the connection of such character that it will be held on the handle against becoming loose or turning thereon to any de 'ree.

aid invention consists of structural features substantially as hereinafter fully disclosed and particularly pointed out by the claims.

In the accompanying drawing illustrating the preferred embodiment of my invention Figure 1 is a perspective view of the hammer or tool. Fig. 2 shows disassembled views of the constituent parts or members of the tool or hammer. Fig. 3 is a broken sectional view, taken through the eye or aperture of the tool or hammer proper.

In carrying out my invention, I construct the same of the member or hammer proper 1, the handle 2 and the'rod or shaft 3. Said hammer proper 1, of the general stone and brick mason type, has a tapering eye or aperture 4:, the contraction or narrowing thereof being toward the inner or front side of the tool, or the handle. The aperture or eye 4 may be circular, rectangular or oval in cross-sectional outline as may be desired and the principle of the invention remain intact.

The handle 2, which may be wooden, is tubular or has a longitudinal opening or passage 5 through it of the re uired cross-sectional outline, and is suita 1y held to the hammer-head or hammer proper, or other tool, by means of the iron or steel shaft 3 having an enlarged inward-tapered outer end 6 corresponding with, and inserted through hammer proper, and passed through an apertured ferrule a fitted upon the outer end of said handle, and also through the opening or passage 5 of said handle, said rod or shaft having applied to and screwing upon its outerend, beyond said handle, a nut 7. Interposed between said nut and end of handle is a preferably leather washer 8 which serves, by its recoil expanding action under the tightening action orpressure of said nut, to effectively retain the latter in fixed position, as against any jarring action transmitted thereto when the hammer or tool is used.

It is noted that, the rod or shaft 3 being flared toward its outer end, where it passes through the hammer-head, in consequence of its inward tapered contour or outline, as the nut 7 is screwed tightly upon said rod or shaft, against the washer 8, said rod will be tightly wedged or forced into the eye or aperture 4 of the hammer-head and the wooden handle 2 be jammed a ainst the latter and the whole thus be rigi ly assembled one upon the other, and yet adapted to be readily separated when it may be desired to remove the hammer-head from the handle for sharpening, or simply the disassembling of the parts for greater convenience in carrying or transporting the tool or im lement.

n considering the structural c aracteristics of my improvements and their mode of employment as hereinbefore disclosed, it is to e particularly borne in mind that the entire invention has been provided with a view to carrying out the purposes set forth at the outset of this specification. In the use of modern steel-headed tools for bricklayers and other artisans great difficulties have the eye or aperture 4 of the hammer-head or I heretofore been met with in keeping the a heads rigidly secured to the handle when the tool is in use, and when the handle has been properly secured then difficulty arose in removing and reconnecting it within proper time and in a proper manner, when the matter of re-sharpening or repairing of the tool was called for. My improvements have been wrought with the purpose, exclusively, of overcoming and remedying the aforesaid difficulties, and this they do and to this they are confined.

I claim I A bricklayers tool comprising a steel-head provided with an inward tapered eye, an ular in cross-sectional outline, a rod-mem er having the eye-engaging end portion tapered in like manner to the eye and formed to fit closely in the latter, the angularity and taper of the end portion of said rod extending some distance inward from the head, a handle having a longitudinal opening therethrough for receiving and conforming in outline to the outline of the rod-member, the latter being screw-threaded on its rearward extremity which screw-threaded part extends beyond the rear end of the handle, a nut adapted to receive a tool for operating it turned on the screw-threaded extremity of the rod-member, and a pliable leather washer interposed between said nut and the end of the handle to which latter it is secured.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN B. ISABEL.
